“I had a long time to stew over again not doing well Down Under. It was very tough… I certainly wasn’t feeling too great about my game after that,” said Isner, who hit 33 aces in the one hour, 14-minute win.

“But the only thing you can do is just continue to keep working hard. For me, keep working on my body. And I used that time to really get stronger. You have to look at it as a blessing in disguise.
